GENERAL DESCRIPTION

VV6300 is a highly-integrated CMOS image sensing

device. In addition to a 160 x 120 pixel image sensor

array, the device includes on-chip circuitry to drive

and sense the array.

The output stage of the sensor contains a successive

approximation circuit which performs analogue-to-

digital conversion of the photodiode array to produce

8-bit or 4-bit pixel data.

The primary image size is 160 x 120 but border pix-

els/lines can be enabled to give an effective image

size of 164 x 124.

VV6300 features electronic exposure and gain con-

trol over a wide range, enabling the use of a single

fixed-aperture lens.

A bi-directional 2-wire serial communications inter-

face allows the device to be configured and its oper-

ating status monitored. The status information may

also be multiplexed onto the digital output bus.

NB. A colour processor will be required to

convert the raw colourised pixel data into colour

image information.
